Description

Technical Field [0001] The present invention relates to a hose connecting structure for a hydraulic breaker,

[0001] The present invention relates to a hose connection structure for a hydraulic breaker, and in particular, it is possible to improve the durability of a product by minimizing the influence of vibration generated during a breaker operation by improving a hydraulic hose connection structure, To a hose connection structure for a hydraulic breaker in which the structure is improved.

Generally, a hydraulic breaker is widely used for crushing concrete or rocks by attaching to a construction equipment such as an excavator, a loader, and the like, and a chisel, which is a crushing tool, The concrete and the rock are crushed by the hitting force which hits the piston up and down.

These hydraulic breakers consist of hydraulic cylinders and pistons, with a chisel on the front of the cylinder used to break the object.

When the piston is reciprocated by the operation of the cylinder, the chisel is hit, and a strong impact is applied to the object, and the object is split or broken.

A valve device is provided at the rear end of the hydraulic cylinder to control the supply of the fluid required for the operation of the piston to one side of the surface of the hydraulic cylinder. The hydraulic oil is temporarily stored on the surface of the hydraulic cylinder adjacent to the fluid control part, An accumulator for use as an energy source is formed.

The valve device includes a valve housing formed on one surface of the hydraulic cylinder, a valve coupled to the interior of the valve housing to horizontally move through the opening of the valve housing to control the supply of fluid, a valve housing to seal the opening, And a valve cover coupled through a plurality of fastening members.

Particularly, in the case of a breaker for crushing a rock or a concrete structure, a relatively large impact is required, and thus high reliability is required in the detachment and hydraulic connection.

For example, "Hydraulic hose connector of an excavator breaker" (Registered Date: 2006.11.02) of Korean Registered Utility Model No.0430686 is a hydraulic hose connector of an excavator breaker, which has a central penetrating portion for progressing hydraulic pressure, An adapter that is fastened and fixed to the hydraulic hose connection portion of the body, and a split type clamp which is fastened to the rear surface of the adapter while surrounding the flange of the hydraulic hose. As a result, a stable connection state of the hydraulic hose can be ensured and the effect of preventing breakage of the hydraulic hose due to an operation shock is expected.

However, when the hydraulic hose connection structure of the existing breaker operates in a state where it is mounted on an excavator, high pressure hydraulic oil flows through the hydraulic hose and flows into the breaker to perform various hitting operations such as excavator shaking, The recoil and the shifting of the position of the impacted object) may cause the hose adapter to break or the metal part of the hose to break and the oil to leak.

As another example, a "hydraulic hose connector for a hydraulic breaker" (Registered on Jan. 01, 2006) of Korea Registered Utility Model No. 0406201 discloses a hydraulic hose connecting portion of a hydraulic hose to which a hydraulic hose extending from an excavator is fastened, So as to prevent the breakage of the hydraulic hose and the adapter which is a fastening mechanism of the hydraulic hose.

In this case, there is a problem that the unit price of the product increases due to the application of the expensive swivel structure.

"Hydraulic hose connector of an excavator breaker" (Registration date: 2006.11.02) of Korean Registered Utility Model No. 0430686, "Hydraulic hose connector for hydraulic breaker" of Korean Utility Model Registration No. 0406201 (registered on January 1, 2006)

The connecting means includes a first connection pipe connected to a hydraulic path of the breaker main body and connected to change the flow path, and a hose adapter connected to the first connection pipe and connected to the first hydraulic hose.

The connection structure of the hydraulic hose for the breaker is not directly connected from the hydraulic pipe of the existing excavator arm to the main body side of the breaker, but is connected to the upper part of the bulkhead by the first hydraulic hose from the breaker main body, The second hydraulic hose is connected to the hydraulic pipe of the excavator arm for securing the turning radius of the excavator arm. In addition, the connection length of the hydraulic hose is shortened, It is possible to reduce the load on the part of the metal member that is generated by the metal plate, thereby improving the durability of the parts.
